So i downloaded the 32-bit iso from homepage, created a live usb, booted up, tried to install Antergos, failed because of the ‘‘cnchi can’t continue’’ problem. Found workaround form this topic, but i can only get to step 3. I see the notification (gnome3) at the bottom that cnchi is updating, but after that - nothing.
